IMPROVEMENT IN SMUT-MILLS.

The Schedule refaxi'edto inthese Letters Patent and making part of the same.

To all whom itmm-y concern:

Be it known that I, DAN IEL PHASE, of Floyd, in the county of Oneida, aml Stat-cot Ncvv. York,"'have invented a new and useful improvement in met-0nstruction of the cast-iron pieces of which the hollow stationary cylinder is composct in my smut-mill, patented by me on the 22d day of September, A. D. 1863; and 1 do licrcby declare that the following is a full; clear, and exact description of the construction and operation of the said improvement, reference being bad to theannexed drawings, and to the letters of reference marked thereon, making a part; of this specification.

' The "object of my improvement is to render more perfect and easier of. construction the spaces for the passage of the dust in cleaning grain, which, in my said patented machine, are left between the small pieces of metal of which thc atbrcsaid cylindcr is formed, it being important that the said spaces be of uniform capacity, and as large as may be,withoutsuffering the grain to pass. And, also, that the said pieces may be so perfectly cast for the )nrpos c of tormiug' the said spaces, that time may not be required in searching for pieces that, being placed opposite to each other, will leave the desired space between them.

These cast-iron pieces, as invented and patented by me, as aforesaid, tormed theseintervening spaces by having a slight indentation alike in both the upper and lower edges, with the il-ltention that when pla -ed opposite to cach-othei-ni building up thccylinder, tl requisite space would be leit between; but .c it has been found that slight impeit'cctions in the tdg'cs ol' the. castings unavoidably occur, and in laying up the cylinder, the slight receding of the edges of two oppositc' pieces would leave the space too wide, letting through the wheat; and in other cases, the variation being in the opposite direction,

the space would be unnecessarily narrow, and much time was required to'tind pieces of suitable charac- .mto properly match each other; and still, with all this care, the cylinder was liable to have some imperfectspaces.

-'lhe. object of my present invention is to remedy this evil, and I do it by making an indentation for the requiredspacc, sutiicientfor that purpose,- all on 'one sidc of thc metal piece, say, the upper side of each piece, the lower edge of all the pieces having a straight line li'om cud to end, so that in building up the cylinder, an indented edge is always opposite to a straight edge. i

I have also improved the picces'u'sed at the junction of the two semicircles in forming the cylinder, which, as described in my former patent, had an eye. for the. reception ofthc vcrtical rod only at one end, the rod Figure 8 is a specimen of all the other pieces composing, the cylinder.

I illustrate these improvements by the annexed drawings.

Figure 1 is a section of the cylinder, where the metal pieces ,A composing it are of the description heretofore patented and constructed by me.

Figure 2 is a. like section, wheret-hc constituent pieces A are according to my-present improvement.

Figure 3 is'a. back view of a single piece of which the cylinder is formed, as heretofore patented and 'constructcd.

Figure 4, a like view of a single piece, made according to theimprovement.

Figure 5 shows a layer of pieces made according tov the former patent, and put together as when laying up the cylinder.

Figure 6 is a similar layer of pieces, made according to the improvement.

Figure 7 shows the character of the pieces which, according to the former patent, lie at tho junction of the two semicircles forming the cylinder, as described in the former patent, and have only one eye, 0, for the reception of the. vertical rod. b and f, Hg. 6, are these junction-pieces, constructed according to the improvi'ement, having two eyes, S and C, for the vertical rods, it being found better to use an eye, S, than to have the rod occupy the angle, (1), ti". 7,) as before constructed.

The comparison of. the metal pieces forming the cylinder, as constructed and used undcrjlny patent, with the same pieces constructed according to the present improvement, is clearly shown in the two figs. 3 and 4, and itis evident that if the cylinder is formed by laying ituplin the manner described in the former patent, of pieces constructed according to the improvement, and shown in fig; 4, the straight edge (I, in the successive layers covering the chasm c, that spaces of uniform capacity would be formed between the constituent pieces throughout the entire cylinder.

As it is also evident, from there being but one complex side in the improved art-icle, the casting (as is found to be the case in actual practice) is made more perfect, and the spaces .in the finished cylinder are. more uniform and perfect also, and less time is re.- quired for laying up the cylinder,'as none is spent in looking out pieces to match each other, in order to form the spaces.

The whole niachine, with the exception of the improvements here described, is constructed, put together, and used the same as described in my former patent.

I do not aim to improve. or change the general character oi principle of the mill, but in the very essential particular involved, ,the improvement in the construction is an important one.

Having, therefore, described nay-improvement and its use,

I claim-- 1. As an improvement in smut-mills, forming the spaces 1), fig. 1, between the metal pieces A', which compose the cylinder, by making the required pr0jeetions, c c, ,fig 4, for forming Sillll spaces B all on one side oi'suiil nieces A, substantially as shown.

2; Constructing the pieces A, with eyes I) G, fig. 8,

on each end thereof, for the reception of the vertical rods 01' bolts D D, Hg. 2, when said parts are arranged as herein shown and described. DAN. PEAS E. Witnesses:
